Bedini L., Bottini S., Herranz D., Kuruoglu E. E., Salerno E., Tonazzini A. Separation of dependent sources in astrophysical radiation maps using second order statistics. In: Astronomical Data Analysis (Sant' Agata sui due Golfi, 28 April - 1 May 2004). Proceedings, pp. 1 - 9. F. Murtagh, G. Longo, J-L Starck and V. de Gesł (eds.).

This paper proposes a semi-blind approach for the separation of sources that are not totally uncorrelated. Up to now, all work on separation of components in astrophysical maps have assumed statistically independent sources. In this work, we attempt to perform a dependent component analysis of astrophysical sources and we propose a semi-blind algorithm which provides separation using second-order statistics only.
